SHOCK-LOADING DEVICE.

To aZZ whom it may concern:

Be it known that I, Monms W. Hoes, a citizen of the United States of America, and a resident of Lincoln township, Blackhawk county, Iowa, have invented certain new and useful Improvements in Shock- Loading Devices, of which the following is a specification.

My invention relates to improvements in shock-loading devices, and the object of my improvement is to supply an apparatus adapted to pick up shocks of corn-stalks or other fodder, carry the same to a depository, and unload it in such depository. This object I have accomplished by means as hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved shock-loading device. Fig. 2 1s a plan view of the said machine.

Similar numerals of reference denote corresponding parts throughout the several views.

The two carrying-wheels 24 are fixed on the ends of a rotary axle 25 seated in bearings in a frame '1. Said frame has a medial longitudinal beam having on the under side of its rear end depending rock arms 5 for the axle of a caster-wheel 4, carrying an integral gear-wheel 30 in mesh with a pinion 29 on the lower end of a vertical shaft 28, the latter seated in a bearing-opening in said beam, and provided with a hand-wheel at its top just in advance of the drivers seat, for easy steering. On the rear end of the said beam is secured the spaced-apart bars 31, in whose ends a double-tree 32 is medially pivoted, carrying the usual pair of swingle-trees 6. On opposite sides of said frame '1, are pairs of uprights 1314 connected at top and bottom but spaced apart. A pulley-sheave 12 is fixed to the top of each pair and contains a pulley over which a cable 16 runs, whose forward end is connected to a ring 17 on a chain 18 on the same side of the machine. The other ends of the cables 16 are connected to and adapted to wind about the drums 23 which are On the inner face of each drum-23 is an integral clutch-member 44 whose toothed Specification of Letters Patent.

face is adapted to fit the toothed face of a clutch-member 46 which has an annular groove 48 adapted to movably receive the ends of shifting-forks 43. The left-hand fork is fulcrumed at its other end on a stud 42 in a bracket on the frame, while the other forkis an integral arm of a bell-crank lever 38 which is pivoted at 45 to a bracket on the frame, and has a third integral arm 40, a link 41 being pivotally connected between the extremity of the arm 40 and an intermediate orifice in the fork-arm 43. To the extrernity of the lever-arm 38 is pivoted the forward end of a longitudinal rod 3 whose rear end is pivotally connected to the lower extremity of a hand-lever 2 which is fillcrumed on the longitudinal beam 1 and has a finger-piece 27 operating a movable detent adapted to adjustably engage teeth on a rack-segment 26.

About each friction-disk 50 is looped a band-brake one end of which is fixedly connected to the frame, while its other end is connected by links 49 and 35 to the crankarm 34, or the crank-arm 37 respectively, on opposite ends of a cross-bar 33, the latter having a hub 9 mounted on the rod 3. A sleeve or stop 10 is secured on the rod 3 just in advance of the hub 9 and adapted to engage the latter at times.

Traveler wheels 22 are seated in the interspaces of the uprights l3 and 14 on each side of the machine, and are mounted to rotate on the ends of a shaft or cross-bar 54. Fixedly projected from said cross-bar are a plurality of forwardly and longitudinally extended and spaced apart fingers 19, which are connected fixedly farther'forward Slack chains 18 are connected on each side between the two said cross-bars just outside of the outermost fingers 19. Each outer finger 19 carries near its rear end on its outer face an antifriction wheel 21 adapted to ride upon the forward face of the abutting upright 14, to prevent binding of the fingers with the upright in moving up or down thereover.

Each end of the cross-bar 54 has an up: wardly-projecting loop 47. To each end of the upper cross-beam 51 which connects the two pairs of uprights 13 and 14, is a lug on its under side having a bearing for the shaft of a depending hook 52, the other end of each shaft having an integral rearwardlyprojecting arm 53 having an eye at itsextremity, between which and the rear upper part of the upright 13 a tension-spring 11 is connected. To the eye in the arm 53 is also connected the forward end of a cable 8, which latter is carried under a pulley on the frame and then back to connect with the lower extremity of a foot-lever 7, the latter medially pivoted in the frame in advance of the hand-lever 2, and with a pedal on its upper end in reach of the drivers foot.

The machine is operated in the following manner: Horses having been hitched to the device and the swingle-trees 6, act to move the device forward, the driver steering by means of the hand-wheel and its shaft 28. The fingers 19 being in the down position shown, but the winding-drums being loose 011 their shaft, the apparatus is directed toward a shock. The fingers 19 pass under the shock, which becomes loaded thereon. The hand-lever 2 is then shifted appropriately to move the rod 3, which in turn moves for ward and shifts the forks 43 to throw the clutches into engagement with the drums. Since the clutches are rotatable with the shaft 25, being slidable over the splines 39 thereon, the drums are put in rotation to wind up the cables 16 and lift the fingers 19 to the top of the upright 14 with their load. Since the collar 10 is moved forward simultaneously with the rod 3, the cross-bar 33 is released and the band-brakes are released from the friction-disks 5O ust as the drums begin to rotate. The machine has been moving forward during this operation, and just as the fingers with their load arrive at the top of said uprights, the loops l7 engage the hooks 5:2, push them forward, until the hooks by reason of the tension of the springs 11 move forward and enter the loops. The load and fingers are then held. suspended, and the driver may shift back the handlever 2, which causes the clutches to disengage from the drums at the same time that the moving back of the sleeve 10 causes it to engage the hub 9 of the cross-bar 33 to push back the latter, and cause the brakes to bind the frictiondisks to hold the drums still, with the cables holding the fingers 19 eX- tended forwardly. Nhen the apparatus has approached a depository, the driver pushes the foot-lever 7, shifting the cable 8, which pulls down the arm 53 and disengages the hook 52 from the loop 47 on each side. The cross-bar 54: being thus released, the load tilts the fingers 19 forwardly and is delivered into the depository. The windingdrums are next released from the brakes to run free and the fingers drop to their first position.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A shock-loading device, comprising a transportable frame containing fixed uprights, a rotary shaft mounted across said frame, a gathering and lifting implement having a plurality of forwardly-directed gathering fingers and movably connected to said uprights to move up and down therealong, a winding-drum loosely mounted on said shaft and having a clutch-face on one end, a slidable non-rotatable sleeve on said shaft having a mating-clutch face on one end for the other said clutch-face, a cable connected to said implement, passed over said uprights, and adapted to be wound upon said drum, detachable connectingmeans between the upper part of said up rights and the end of said implement which abuts upon the uprights, comprising a catch on said uprights, engaging-means on said implement adapted to enter into detachable engagement with said catch when the implement is at its uppermost position, and means for releasing said catch from said engagingmeans to permit the implement to return to its first position.
